asflt'o 'enable l'oca'ting'a tool-head 'to-one or both'si'desof and insp'aced're'lationto a work table. I p p I Still a 'furitherobjet 'of theinvention is to afford mechanism in conjunction with a crank planerforsimultaneously feeding toolheads'loc'ated respectively above and toone side of the work for cooperation with the top and sides thereof,such feeding being ef fected simultaneously and in a predeterminedrelation. 7

With these ends in view, the invention comprises the construction thatwill appear clearly from the following description when read inconjunction with the accompanying drawings, the features of noveltybeing pointed out in the claims following the description.

In the drawings:

Figure 1 is a front elevation of a conventional crank planer havingapplied thereto one embodiment of the invention;

Figure 2 is a side elevation of the same, and

Figure 3 is a horizontal sectional view taken on the line indicatedgenerally at 3-3 of Figure 2. k

Referring more particularly to the drawings in which like referencenumerals refer to the same parts in different views, 1 designates a baseor bed upon which is mounted a work table 2 for reciprocatory movementwith relation to the tools. The work table 2 is given a quick returnmovement through the action of crank mechanism that is controlled fromthe motor 3 and operatively connected with the work table through partssuch as are well known in the art and therefore unnecessary toillustrate in detail.

4 and 5 designate uprights or standards upon which is mounted forvertical adjusttool-hea ds- -need not necessarily be: the same,

ment the crossrailtihaving atool-head 7 mov- I able thereon and adaptedto support a tool for cooperation with the upper surface of the work.The upright '5 extends to a point beneath the top of the work table, andis spaced laterally at one side thereof. The standard 5*is adapted toreceive a side tool head 8 which can be fed vertically on the standardfi'beneath the crossrail, and is movable to a position beneath the topof the-6 table, as illustrated in Figure lso as to bring its tool intocooperative relationship with a side of the work, this arrangementpermitting simultaneous operation upon-the top and a side of the Work.Under suchconditions it 6 is desirable to provide for simultaneouslyfeeding both the-top and side tool hjeads, and

this is accomplished by the following mechanism. 1 The crank shaft,which effects movement of the iwork' table, is provided with a crank 10,see Figurefi, andcrank arm 11 connected to amend of arocker arm 12; Therocker arm 12 1 is pivoted at 13 1 and {ha-s its opposite end-'14connected to anactuating devicepreferably comprising a vertically'arranged re- 'ciprocatory rack 15' which cooperates with a "suitablegear formingpart of a feed mechan-ism designated generally at 17 foreffecting the necessary lateral feeding of theltop toolhead 7 oncrossrail 6, through a screw 18.

Theside'tool-headdis fed by a'vertical screw 19 extending throughthestandard. 5 which carries at itslower en d' abevel pinion 20 enga'gedby a bevel pinion 21. The latter is controlled vthrough gearingincluding pinion 22, gear 23, and gear 24, see iFigurei-S, the; gear 24being engaged and actuated by the aforementioned actuating device on.rack 15 'at'thedower'end of the latter. I It will be understood-thatonefof the gearsin the trainfjustreferred'to has an operating movernentonly in Zone direcion, as welliknownin this ty-peof feeding mechanisms,andthat :duringtheoperatingstroke of the 'rack15, the 9 mechanism justdescribed-serves tomovathe side i tool-head *8 verticallygat the a same.time that the top tool-head 7 is fed 1 horizontally. The amount offeeding of the respective 26 extending around pulleys 27 and 28 andthence downwardly through the opening 29 in standard 5, which servesalso to house the aforementioned vertical screw 19.

Although only one side-head has been.

shown and described, the construction of upright 5 and its side-head 8may be duplicated for upright e, affording tools and tool controllingmechanism on both sides of the work table, similar to that alreadydescribed.

While the invention has been described with reference to a particulararrangement, it is not confined to the precise details herein set forth,but may be modified within limitations Without departing fromthe primaryaccomplishments of the improvement or the scope of the following claims.

a I claim:

1. In a crank planing machine, the combination with a work table and c'ank mechanism for imparting a quick return movement thereto, said crankmechanism including a crankshaft for controlling movement of the Worktable, of uprights, a crossrail adjustable on said uprights, one of theuprights extending to a point beneath the top of the work table andspaced laterally therefrom, a tool head movableon, the crossrail, asecond tool head movable on the last named upright to 'a point beneaththe top of the work table and opposite one side thereof, feedingmechanisms for the tool heads, a common actuating device cooperatingwith said feeding mechanisms, and a crank on the aforesaid crank shaftoperatively connected to said common actuating device.

2. In a crank planing machine, the combination with a work table andcrank mechanism for imparting a quick return movement thereto, ofuprights, a crossrail adjustable on said uprights, one of the uprightsextending to a point beneath the top of the work table and spacedlaterally therefrom, a tool head movable on the crossrail, a second toolhead movable on the last 'nameo upright to a point beneath the top ofthe work table and opposite to one side thereof, a feed screw arrangedvertically in said upright for controlling the last mentioned tool head,feeding mechanism located at the bottom of said upright below the worktable and operatively connected to said feed screw, of feeding mechanismfor the first mentioned tool head, a common actuating device cooperatingwith said feeding mechanisms and operating to simultaneously feed thetool heads laterally and vertically respectively, and operativeconnecting means between said crank mechanism and said actuating device.

3. In a crank planing machine, the combination with a work table andcrank mechanism for imparting a quick return movement thereto, saidcrank mechanism including a crank shaft for controlling movement of thework table, of uprights, a crossrail adjustable on said uprights, one ofthe uprights extending to a'point beneath the top of the work table andspaced laterally therefrom, a tool head movable on the crossrail, asecond tool head movable on the last named upright to a point beneaththe top of the work table and opposite one side thereof, a feed screwarranged in said upright for controlling the last mentioned t-ool head,feeding mechanism located at thebottom of said upright below the worktable and operatively connected to said feed screw, feeding mechanismfor the first mentioned tool head, acommon actuating device cooperatingwith said feeding mechanisms and operating to simultaneously eed thetool heads laterally and vertically respectively, a crank on theaforementioned crank shaft, and a connection between said crank and saidcommon actuating device.

In witness whereof, I have hereunto signed my name.

ALFRED TROSCH.
